Objective: To evaluate the incidence of malposition of the ovary in pa
tients with uterine anomalies compared to patients with a normal uteru
s. Methods: Ovarian malposition was investigated in 1082 patients via
laparoscopy. Only ovaries in which the upper pole was attached to the
area above the common iliac vessels were designated as malpositioned;
often the lower pole was attached inside the pelvis. These patients we
re divided into two groups. Group I consisted of women with congenital
uterine anomalies (divided into subgroup A, congenital absence of the
uterus and unicornuate uterus, and subgroup B, other uterine anomalie
s). Group II included those women with a normal uterus (control group)
. Results: The incidence of malposition of the ovary was higher in gro
up I than group II (P <.001). When we separately compared subgroup A a
nd subgroup B with the control group, only subgroup A had a significan
tly higher incidence (P <.001). Conclusion: Our results reveal that th
e incidence of malposition of the ovary is higher in patients with con
genital uterine anomalies than in a control group. This is especially
true when the uterus is absent or is only partially present.
